[Typo3] Max width of enlarged image is only 1000 ?

[Francesco di Francia]

Also, just realized now, the code:

parseFunc.tags.link.typolink.JSwindow_params = scrollbars=1,resizeable=1

seems not working because the image need a vertical scroll bar and it's 
not appear. The image need it because there's the bottom bar of the 
popup windows that hidden the last bottom part of the image.
Maybe i'm wrong but it seems that the JSwindow doesn't take in account this.
